/edit-target-prompts — Target Prompt Asset Editor

This skill is the only way to read or modify .claude/ files in the target repo. Direct Read/Edit/Write calls to files under the target repo's .claude/ directory are forbidden — use this skill instead.

Why

Every prompt asset change must be:

1. Logged — recorded with timestamp, sha1, and diff stats
2. Diffed — the full unified diff is shown before and after edits
3. Auto-committed — so the change survives git reset --hard HEAD~1 discards
4. Traceable — so the researcher can correlate prompt changes with metric changes

Available Assets

Use pixi run target-dot-claude-list to discover available assets. You can also use paths relative to .claude/ (e.g., rules/some-rule.md, skills/run/SKILL.md).

Actions

List all assets

pixi run target-dot-claude-list
pixi run target-dot-claude-list --json

Read an asset

pixi run target-dot-claude-read skill
pixi run target-dot-claude-read rules/pipeline-structure.md

Edit an asset

To edit, you must:

1. Read the current content with target-dot-claude-read
2. Prepare the new content
3. Pipe it to target-dot-claude-edit:

echo "new content" | pixi run target-dot-claude-edit skill

In practice as Claude Code, the workflow is:

1. Bash("pixi run target-dot-claude-read skill") — read current content
2. Make your changes to the content
3. Bash("pixi run target-dot-claude-edit skill <<'PROMPT_EOF'\n<new content>\nPROMPT_EOF") — write and get diff

Diff without writing

echo "proposed content" | pixi run target-dot-claude-diff skill

This is the same pattern the supervisor uses

The supervisor edits the researcher's .claude/ files via pixi run dot-claude-edit. The researcher edits the target's .claude/ files via pixi run target-dot-claude-edit. Both use the same harness_core.prompt_editor functions underneath — logged, diffed, auto-committed.
